Abstract Arrays of lumped-element kinetic inductance detectors (LEKIDs) optically coupled through an antenna-coupled transmission line are a promising candidate for future cosmic microwave background experiments. However, the dielectric materials used for the microstrip architecture are known to degrade the performance of superconducting resonators. In this paper, we investigate the feasibility of microstrip coupling to a LEKID, focusing on a systematic study of the effect of depositing amorphous silicon nitride on a LEKID. The discrete and spatially separated inductive and capacitive regions of the LEKID allow us to vary the degree of dielectric coverage and determine the limitations of the microstrip coupling architecture. We show that by careful removal of dielectric from regions of high electric field in the capacitor, there is minimal degradation in dielectric loss tangent of a partially covered lumped-element resonator. We present the effects on the resonant frequency and noise power spectral density and, using the dark responsivity, provide an estimate for the resulting detector sensitivity.

BSCCO/Ag-based RLC resonators have been assembled and characterized with the aim of studying the behaviour of such conductors when subjected to a radiofrequency current flow. The inductive part of the circuits is constituted by several turns of a multifilamentary BSCCO/Ag tape fabricated by the Powder-In-Tube method, and treated in such a way that the outer silver sheath is completely removed. A high-Q multilayer capacitor is directly soldered between the extremities of the superconducting tape, its value being chosen in order to tune the resonance frequency around 10 MHz. The quality factor of the assembled RLC circuits has been characterized as a function of the induced current, in order to relate the observed dissipative behaviour to the current penetration mechanism occurring in the superconducting tape.
